562 FAUNA HAWAIIENSIS 



(20) Oligota swmlans, Blackb. 



Oligota simulans Blackburn, Tr. Dublin Soc. ser. 2, in. p. 123. 

 I think this species is certainly near to O. gymnusa, though it comes from a 

 different island. 



Hab. Kauai, Waialeale. A single specimen by beating branches of trees, 2000 ft. 

 (Blackburn). 



(21) Oligota mutanda, Sharp. 



Oligota mutatida Sharp, Tr. ent. Soc. London, 1880, p. 46, 



This insect is narrow, and is of very dark colour; there is usually a very faint 

 metallic reflection from the upper surface; the punctuation is scanty but rather coarse 

 and rough. The legs are always very dark, sometimes quite black, and they are 

 slender. The antennae are yellow, but they are slightly darker at the tip, sometimes 

 strongly so. I see no distinct indication of a suture on the breast between the coxae. 

 Nine specimens. There is also one from Maui that seems quite the same. 



Hab. Hawaii, Maui. — Hawaii, Mauna Loa, 4000 ft. (Blackburn): Kilauea, viii. 

 1895, VIII. 1896, IX. 1896, and also x. 1896; Kona, 5000 ft. 30. vi. 1892 ; (Perkins). — 

 Maui, 5000 ft. X. 1896 (Perkins). 



(22) Oligota oahuensis, sp. nov. 



Angusta, fusca, antennis pedibusque testaceis, illis brevibus, subtiliter crebre 

 punctata, brevissime pubescens. Long, i^ mm. 



Closely allied to O. miitanda, rather smaller and paler in colour, with finer punctua- 

 tion and pubescence, and rather shorter antennae, the 4th joint of which is not longer 

 than broad. Seven examples from Oahu and one from Lanai agree satisfactorily ; the 

 five individuals from Kauai are darker in colour, but may well be the same species. 



Hab. Kauai ?, Oahu, Lanai. — Kauai, mts. Waimea, 4000 ft. vi. 1894. — Oahu, back 

 of Tantalus, VIII. 1900; Konahuanui Ridge, xii. 1900. — Lanai, 2000 ft. 1894. (Perkins.) 



(23) Oligota haleakalae, sp. nov. 



Angusta, fusca, antennis pedibusque testaceis, illis sat elongatis ; crebre subtiliter 

 punctata, brevissime pubescens. Long, fere 2 mm. 



This is extremely closely allied to O. oahuensis but distinctly larger, and with more 

 elongate antennae. One specimen. 



Hab. Maui, 5000 ft. v. 1896 (Perkins).
